JAMES F. THAYER, OF PROVIDENCE, RHODE ISLAND.

BUTTON FASTENER.

SPECIFICATION forming part of Letters Patent N 0. 358,507, dated March 1, 1887.

Application filed December 4, 1886. Serial No. 220,675. (No model.)

To all whom it may concern:

Beitknown that 1, JAMES F. THAYER, a citizen of the United States,residing atProvidence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Button-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My present invention relates to a new and usefulimprovement in button-fasteners styled staples, and it consists, primarily, of a wire fastener comprising a central buttonloop cylindrical in form, aliattened portion on each side thereof, and two cylindrical attaching-prongs with sharpened or attenuated points, said fastener adapted to be used in connection with an eye shank button or to be combined with a head portion rigidly secured to the central button-loop, all as will be hereinafter more fully described.

Figure 1 is a perspective view of my improved fastener. Fig. 2 is a like view of the same with an eyeshank button as secured to fabric. Fig. 3 represents my improved fastener combined with a head portion rigidly secured thereto. 7

In forming the fastener round wire is pref erably employed. It is first cut to a given length and manipulated by proper machinery, which bends and swages the wire into the re' quired shape. The central portion of the wire is bent to form the button-loop l for the re ception of the button. On each side of said button-loop the wire is rolled or broadened to form bearings or flattened portions 2 2, termi nating in downwardly-projecting prongs 3 3, bent at right angles to said flattened portions, said prongs being provided with sharpened or attenuated points, the button loop and prongs being cylindrical in form, or of the form or configuration in cross-section as the wire from which the fastener is made, as fully shown in Fig. 1 of the drawings.

In securing a button to fabric, the wire eyeshank is passed sidewise onto one of the prongs 3, and over the flattened portion 2, to take advantage of the elongated shape of said button-eye shank, which allows the flattened portions to be broadened considerably wider than the wire from which the fastener is made. When the central loop is reached, the button is turned upright and the fastener is secured to fabric, as shown in Fig. 2, the flattened portions 2 2 forming a firm bearing on the upper surface, the cylindrical form of the central loop enabling the button to move freely in all directions, while the cylindrical prongs, with sharpened or attenuated points, allow an easy penetration and a secure clinch in the fabric.

By forming the central button -loop, 1, a trifle longer than is required for an eye-shank button, the fastener may be provided with a head portion, at, rigidly secured thereto by compressing or molding upon said central button-loop, thus making a desirable combined button and fastener, as shown in Fig. 3 of the drawings.

Having described my invention, I claim-- 1. A buttonfastener comprising a central button-loop cylindrical in form,a flattened portion on each side thereof, and two downwardlyprojecting cylindrical attaching-prongs with sharpened or attenuated points, as set forth.

2. The button fastener herein described, consisting of a central buttondoop cylindrical in form, a flattened portion on each side thereof, and two cylindrical attaching-prongs with sharpened or attenuated points, in combination with a button-head rigidly secured to the central button-loop of said fastener, substantially as and for the purpose specified.

In testimony whereof I affix my signature in the presence of two witnesses.

JAMES F. THAYER.
